一种基于参数调制的混沌数字通信方法

该文提出了反馈同步方法，并基于此方法提出了一种利用混沌载波进行数字通信的方法，该方法通过调制混沌系统中的参数来将二进制数字信号映射为混沌载波，并在接收端利用由可与发送端混沌系统同步的混沌系统组成的接收机对混沌载淡皮进行解调，最后进行了数值领导 具，结果说明了所提方法的有效性。

An Approach Based on Parameters Modulation for Chaos Digital Secure Communication

In this paper, an approach for synchronizing chaotic system is developed by using feedback control theory. The proposed method is then applied to suggest a scheme of digital secure communication using a chaotic carrier. In the transmitter, the bits are mapped to chaotic carriers by modulating parameters of chaotic system. Then the bits are demodulated by the receiver that consists of synchronizable chaotic systems. The numerical simulation results demonstrate the proposed scheme effectiveness.
